The Impact of Dose Reduction of Bacillus Calmette-Guerin on Oncological Outcomes and Toxicity in Non-Muscle Invasive Bladder Cancer: A Systematic Review and Meta-Analysis.

Background: Bacillus Calmette-Guerin (BCG) is the standard adjuvant treatment for intermediate and high-risk non-muscle invasive bladder cancer (NMIBC) following transurethral resection of the bladder (TURB). However, the optimal dose, strain, and schedule of BCG remain unclear.

Objective: To evaluate the impact of BCG dose reduction on oncological outcomes and toxicity in patients with non-muscle invasive bladder cancer.

Complications and adverse events in lymphadenectomy of the inguinal area: worldwide expert consensus.

Background: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes.

Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer.

Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL).

Materials And Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included.

A Th2-score in the tumor microenvironment as a predictive biomarker of response to Bacillus Calmette Guérin in patients with non-muscle invasive bladder carcinoma: A retrospective study.

Intravesical Bacillus Calmette Guerin (BCG) is the gold standard therapy for intermediate/high-risk non-muscle invasive bladder cancer (NMIBC). However, the response rate is ~60%, and 50% of non-responders will progress to muscle-invasive disease. BCG induces massive local infiltration of inflammatory cells (Th1) and ultimately cytotoxic tumor elimination.

Should continuous bladder irrigation be recommended when single instillation of intravesical chemotherapy cannot be used after transurethral resection in low-risk non-muscle invasive bladder cancer?

Reducing the recurrence rate in patients with low-risk non-muscle invasive bladder cancer patients is a critical concern in the urologic community. The gold standard treatment is single instillation (SI) of intravesical chemotherapy after transurethral resection of bladder tumor (TURBT), but unfortunately, it is underused. Continuous bladder irrigation (CBI) after TURBT is an alternative strategy to SI for the prevention of bladder tumor implantation and recurrence.

Post-Transurethral Resection of Bladder Tumor Bladder Perforation Resulting in Mitomycin C Extravasation, Pudendal Neuralgia, and Ureterohydronephrosis.

Mitomycin C (MMC) extravasation after transurethral resection of bladder tumor (TURBT) is a rare and highly morbid complication. Management of these cases may require a multidisciplinary approach with strategies ranging from conservative management to surgical intervention. We present a 48-year-old woman who received a TURBT for a 5 mm bladder tumor.

Prostate Cancer in Latin America: Challenges and Recommendations.

Prostate cancer (PCa) is the most frequent tumor among Latin American (LATAM) men. The incidence of de novo metastatic PCa is higher in LATAM than other parts of the world, and demographic changes in the region have increased disease burden. However, region-specific information regarding prevalence, progression, and treatment effectiveness is not currently available for nonmetastatic, castration-resistant PCa (nmCRPC).

Histologic changes after urethroplasty using small intestinal submucosa unseeded with cells in rabbits with injured urethra.

Objective: To determine whether small intestine submucosa has the same regenerative capacity when urethroplasty is performed in injured urethras.

Methods: Our experiment was conducted in 30 New Zealand male rabbits, all of which had urethral injury. One month after the injury, the animals were randomized into a control group or a group with onlay urethroplasty with small intestine submucosa.
